Puerto Rican nationalists
Puerto Rican nationalists Oscar Collazo and Griselio Torresola failed to assassinate this man. Tom Pendergast suggested this man run for the Senate, and his namesake committee investigated World War II defense contracts. Congress passed the Taft-Hartley Act over this president's veto, and he issued Executive Order 9981, which desegregated the armed forces. This president's namesake doctrine provided aid to Turkey and Greece to help contain communism. For 10 points, name this man who decided to drop an atomic bomb on Hiroshima shortly after succeeding FDR.
